There comes a point, where the conditions and your boat, don't match,
and you just have to slow down. You might be able to find some
doo-hickey, that will extend this point, but you need to decide if it's
worth it, for wear and tear on your equipment and yourself and passengers.
BG There's nothing wrong with going slow on the water ..... I've been
doing it for years ..... EG course, there's something to be said for
driving at the limits through a nasty head sea.......

When cruising with my merc 5.0 alpha 1 on my 22 ft Sea Ray EC, I
occasionally experience what I think is cavitation when encountering rough
or choppy water at speeds around 35 mph. To get out of this condition,
adjusting the trim has little effect and sometimes it is necessary to come
off plane. I know there are some devises that can be attached to the
outdrive to help with this. Does anyone have any experience with this that
could perhaps recommend a solution?

When I refer to cavitation, the condition causes an increase in RPM and a
decrease in speed and is caused by the prop is not making proper contact
with the water, due to too much air around it.
